Answer 1

 (257+90-81)+(81:9+49:7+36:6+64:8)+(99-32+78+66+102+12+1002-567)
efectuam operatiile din paranteze. unde avem prima data inmultiri sau impartiri in paranteze le efectuam pe alea
(347-81)+(9+7+6+8)+(67+78+66+102+12+1002-567)=
=266+(16+6+8)+(145+66+102+12+1002-567)=
=266+((22+8)+(211+102+12+1002-567)=
=266+30+(313+12+1002-567)=
=296+(325+1002-567)=
=296+(1327-567)=
=296+760=1056
